SMOKING PIPE Filed May 14, 1964 INVENTOR. FRED L. WEBER ATTORNEY United States Patent fiice Patented Feb. 7, 1967 This invention relates to a smoking pipe that is molded from any desirable material, such as plastic and with the pipe having multiple conduits for control of the smoke and the saliva and with the pipe being formed in two mating sections to facilitate the molding and with the sections being subsequently permanently united together.

An object of the invention is to provide a molded smoking pipe having a bowl portion for detachable reception of an inner tobacco receptacle and a stem portion in which the conduits are formed and with the conduits leading into a common duct formed in a reduced portion of the tail portion of the pipe and over which is fitted a mouthpiece.

A further object of the invention resides in a molded pipe having a bowl portion and a stern portion and with the stem portion being provided with an upper horizontal conduit for the passage of smoke to a mouthpiece and an inclined conduit extending from the bowl of the pipe to join the smoke conduit and with a removable and renewable filter element that is engageable within a recess to overlie the two conduits for filtering the smoke and to also form an absorbent pad for the saliva that feeds downwardly through the incline conduit.

Novel features of construction and operation of the device will be more clearly apparent during the course of the following description, reference being had to the accompanying drawings wherein has been illustrated the preferred form of the device and wherein like characters of reference are employed to denote like parts throughout the several figures.

In the drawings:

FIGURE 1 is a composite view of a pair of molded pipe sections and a mouthpiece, omitting the filtering element and the supporting means therefor,

FIGURE 2 is a top plan view of the pipe in the assembled form,

FIGURE 3 is a longitudinal section taken substantially on line 33 of FIGURE 2,

FIGURE 4 is a transverse vertical section taken sub stantially on line 44 of FIGURE 2, and

FIGURE 5 is a transverse section taken substantially on line 5-5 of FIGURE 2.

Referring specifically to the drawings, there has been provided a pair of pipe sections A and B. The sections A and B are substantially identical and have mating erigagement with each other and permanently bonded together. Each section A and B is provided with a semicylindrical conduit 5 and an inclined semi-cylindrical conduit 6. The conduits 5 and 6 are molded into a stem portion 7 and the stem portion 7 terminates in a reduced tapered end 8 and the conduits 5 and 6 connect together at the point 9 and lead into asingle conduit 10 that eX- tends through the tapered end portion 8. The end portion 8 is adapted to receive a mouthpiece 11 and the mouthpiece is provided with a tapered socket 12 that may have frictional contact upon the extension 8 or it may be cemented thereto as may be found desirable.

The stem 7 carries a bowl 13 of conventional shape and the bowl at its upper open end is provided with a relatively small head 14, for a purpose to be presently described. Removably engaged within the bowl 13 is a tobacco receptacle 15, provided upon its bottom with a metallic washer 16, that is threaded to receive a fastening screw 17 that passes through the opening 1i; that is formed in the bottom of the bowl 13 and whereby to lock the receptacle 15 in engagement within the bowl. The opening 18 is countersunk at 19 to receive the head of the screw 17.

Rearwardly of the bowl 13 there has been provided a generally square or rectangular recess 21 that is open at its top and receives an absorbent filter element 22 carried by a U-shaped spring holder having flat spring arms 23 that are connected by a head portion 24. The head portion 24 receives a shouldered button 25, through the medium of which the filter element may be removed from the recess. The side walls of the recess, see particularly FIGURE 5 are notched at 26, to receive curved end portions 27 of the arms 23 and whereby to yieldably hold the filter within the recess 21 that is jointly formed by the two sections A and B.

In the forming of the pipe, the sections A and B are molded in a suitable plastic mold, forming the bowl 13, the stem 7 and the conduits 5 and 6. The sections A and B are subsequently bonded together by a suitable plastic cement to permanently unite the sections A and B together to form cylindrical conduits 5 and 6 and the tapered end portion 8. The tobacco receptacle 15 is then inserted into the bowl 13 and anchored therein by the screw 17 and with the tobacco receptacle 15 being centered by the rib 14, that spaces the receptacle 15 from the inner side walls of the bowl 13 to provide for expansion and contraction of the receptacle 15. The receptacle 15 is provided with a top flange 15' that overlies the upper open end of the bowl 13 and a gasket 15b is disposed between the flange 15' and the top edge of the bowl 13 so as to substantially seal the bond with respect to the receptacle. The flange 15' of the receptacle 15 is provided with a circumferential row of relatively small holes 15c into which may be disposed a vaporizable material having a particular odor that is released by the burning of the tobacco and that emits an odor that is adapted to disguise the ordinary smell of a pipe. The receptacle 15 is provided with an aperture i154: adjacent its bottom and whereby the smoke from the burning tobacco is drawn through the aperture 15a to circulate around the bowl 15 to pass through the filter and through the conduit 5 to the mouthpiece.

In the use of the device in the assembled form as illusstrated in FIGURES 25, tobacco is inserted within the receptacle 15 and ignited, as is customary. Smoke is drawn through the aperture 15a, around the receptacle 15 through the filter and through the conduit 5 to the mouthpiece 11. Saliva normally present in a smoking pipe then travels downwardly through the inclined conduit 5, to be absorbed by the filter 22.

It will be apparent from the foregoing that a very novel form of smoking pipe has been provided. The forming of the device is unique since the two halves of the device are molded in the usual injection mold commonly employed in plastics and a web portion of the stem 7 has been cut away, as indicated to substantially reduce the weight of the device. The head 14 provides a clearance between the inner wall of the bowl 13 and the receptacle 15 to permit expansion and contraction of the receptacle and to permit it to be easily removed from the bowl. The device is simple in construction, is strong, durable and most effective as a smoking pipe to prevent the harmful elements of the smoke from being drawn into the mouth of the user. The filter is quickly and easily removed by engagement with the button 25 and permitting the removal or substitution of the pad 22. The receptacle 15 may be formed of any desirable material such as that commonly recognized in smoking pipes.

It is to be understood that the invention is not limited to the precise construction shown, but that changes are contemplated as readily fall within the spirit of the invention as shall be determined by the scope of the subjoined claims.
